Christ did not suffer eternally in any way.
He did however go to Hades, Christ was in Paradise the same day He died.
Christ was in the place of the dead for 3 days and nights.
Paradise was the place of the righteous dead who were awaiting Christ to come to perfect them and so that they could have eternal life, and not perish in hades.
1 Peter 3
18
For Christ also suffered once for sins, the just for the unjust,
that He might bring [f]us to God, being put to death in the flesh but made alive by the Spirit, 19 by whom also He went and preached to the spirits in prison, 20 who formerly were disobedient, [
g]when once the Divine longsuffering waited in the days of Noah, while
the ark was being prepared, in which a few, that is, eight souls, were saved through water. 21 There is also an antitype which now saves us—baptism (not the removal of the filth of the flesh, but the answer of a good conscience toward God), through the resurrection of Jesus Christ, 22 who has gone into heaven and is at the right hand of God, angels and authorities and powers having been made subject to Him.
The old testament saints at death went to 'Abraham's Bosom' which is also called Paradise. And they were separated from any torments of hell, but each on each side could see and talk to the other side, but they could not cross over from the place of torment to Paradise.
Christ did not suffer torment in hades. But before were in the heart of the earth, Christ descended into depth of the earth at his death.
Hebrews 11, the faith of the old testament saints of God, on their deaths did not have eternal life in heaven, they had to wait for Christ to deliver them from paradise in hades . No one has eternal life in heaven with God apart from Christ who is the way into Heaven. No one has ascended into heaven except Christ, and we follow along with Him into heaven, Christ led the captivity captive when He ascended.
Hebrews 11
30 By faith the walls of Jericho fell down after they were encircled for seven days. 31 By faith the harlot Rahab did not perish with those who [
j]did not believe, when she had received the spies with peace.
32 And what more shall I say? For the time would fail me to tell of Gideon and Barak and Samson and Jephthah, also
of David and Samuel and the prophets: 33 who through faith subdued kingdoms, worked righteousness, obtained promises, stopped the mouths of lions, 34 quenched the violence of fire, escaped the edge of the sword, out of weakness were made strong, became valiant in battle, turned to flight the armies of the aliens. 35 Women received their dead raised to life again.
Others were tortured, not accepting deliverance, that they might obtain a better resurrection. 36 Still others had trial of mockings and scourgings, yes, and of chains and imprisonment. 37 They were stoned, they were sawn in two, [
k]were tempted, were slain with the sword. They wandered about in sheepskins and goatskins, being destitute, afflicted, tormented— 38 of whom the world was not worthy. They wandered in deserts and mountains,
in dens and caves of the earth.
39 And all these, having obtained a good testimony through faith, did not receive the promise, 40 God having provided something better for us, that they should not be made perfect apart from us.
